Windows 10: Manufacturers discontinuing drivers release among windows updates

Ok I have posted earlier that my lenovo conexant audio driver with dolby speakers acts faulty with windows update 1803 (No sound output) and i have been having no luck contacting their support as apparently support now is only granted within warranty span in my region .

Now I found out that lenovo has adopted a new trend of posting which of their laptops had been "tested" on various windows updates and pointing that if device is not listed in its test result lists then it is not "eligible" for the update .

Now apparently lenovo realized that windows 10 is going to stay for a while and has no plans to continue supporting /updating all their laptops device drivers as Microsoft do their schematic changes . so all they do now is checking if what's already there would work or not . (Now I realize why this laptop is performance degraded miserably on creators fall update 1709 as its not on its eligible list)

Now this calls for a little brain storming now :

- Does this mean whichever laptop with drivers that fail to work / malfunctions on a certain windows update is stuck to previous build ?

- Will windows continue to update older windows builds as it does for the new ones security / maintenance wise ?

- Are we on verge of an era where windows users will start manipulating drivers just like linux users do all the time or maybe driver moder communities will rise to do so ?

- Can one now go back a build ? for example if i was happier with laptop's performance on build 1703 , is there a mean i can downgrade back to that build and expect windows to continue its maintenance to it ?

- Are we expecting now certain apps / programs to be released to certain windows builds with no backward compatibility ?

P.S Relaying on windows default device drivers isnt always the answer since the manufacture driver is usually more optimal with added features , applications , controllers , higher volume . one can hardly trade that for a (going by) state so please refrain from that advice .
